I beat the crap out of one of my cats and toss her up in the air all the time, but only because she's weird and loves it. I'll do that and walk away, then she'll come running to me crying for more. My other cat on the other hand does not enjoy being roughhoused so he just gets gentle petting.

Honestly, your "friend" doesn't sound like a really good friend, especially since you claim that she lies to you all the time. I would keep better company if I were you. If you tried talking to her and she wasn't interested, there's not much else you can do. Unfortunately, many people own pets that they're not (mentally) equipped to care for, and there's not much you can do unless you can prove that they're being extremely negligent and harmful to the animals.

I work as a technician at a cat only veterinary practice and its really hard to lump cats into any one category. I've seen some who love being man handled and "beat up" we have one that you can roll on her back, shake her, spin her around, and when you walk away she comes back and rubs your legs. Most cats are weird. I've seen a handful that make angry noises, hisses, growls, and grumbles the whole time you pet them and they're rubbing and being super sweet. I've also seen a cat be really nice then turn and attack her owner with claws and teeth hard enough to send the owner to urgent care.
Deliberately provoking a cat is abuse, rough housing and occasional teasing is not. Try talking to Danielle again Little Leaf. Don't necessarily say she's abusing her cat because she'll get defensive. She just may not understand she's being too rough. Ask her about what her cat likes to do for fun and suggest games that are less likely to be rough. Like laser pointers or pulling a string for kitty to chase.
Roughing up young cats often makes them calmer adults (a lot of times the easiest cats to handle for us are the ones raised with little kids) but deliberately provoking the cat will lead to someone being bit, and trust me cat bites can get nasty fast.

Well I don't think the poster that said they beat their cat up meant they hold it down and kick it/hit it until the cat is a quivering mess.

I play very roughly with one of my cats and he does enjoy it. He plays equally as rough with the dogs as well so that's just how he is. He also bites me really hard during play and scratches you if you over excite him.

Also, cats aren't always very tolerant of strangers. Just because it bit you doesn't mean it is abused or afraid of people. Our cats all run and hide when guests arrive. They're not really like dogs that will go over to people for a pat. Usually the person cats seek out is the one who either doesn't like them or isn't paying an attention to them.

If feel like a lot of people is picking on the poor girl and only try to find a way to make things worse. This girl is more mature at her age than the people that criticize her.
